Abstract

The IT industry is hyper-competitive, dynamic and influenced by network effects. To remain competitive, IT vendors need to constantly innovate, improve product strategies, and manage relationships with other organizations. The first essay of this dissertation focuses on the impact of product compatibility strategies taken by IT firms. Using an event study approach this essay assesses the impact of IT compatibility initiatives on firm value. Specifically, it focuses on the performance implications of the “what” (proactive or reactive IT product compatibility strategies), “how” (inter-firm compatibility approach taken), and “when” (stage of completion of the compatibility initiative when announced) aspects of IT firms’ product compatibility initiatives. After analyzing market reactions to announcements of compatibility initiatives collected over an 8-year period, we find that investors respond more positively to compatibility moves that are strategically proactive and were recently launched rather than those that have been completed. Furthermore, firms joining an existing multi-firm compatibility initiative receive a more positive return than firms launching a “would be” multi-firm compatibility alliance. The second essay is in the context of open data mobile apps, which make use of government provided open data to deliver information to individuals. As mobile technology becomes a critical part of everyday life, it is important to understand the factors that influence the adoption of mobile apps. However, even given the touted importance of the open data movement, the adoption and use of open data through mobile apps has been under-investigated. Drawing from IS success literature, this study views the open data mobile app as an IT artifact or an information processing system. We focus on the effect of an open data app’s information quality and system quality on its adoptions. Specifically, we empirically investigate how the dimensions of information quality (i.e., completeness, currency, and format) and system quality (i.e., accessibility and integration) influence open data mobile app adoption.
